IRQ 9 (On the PD6722, this output may alternately be used as an ISA bus DACK* signal)  
IRQ 10 (On the PD6722, this output may alternately be used as an ISA bus DRQ signal)  
IRQ 11  
IRQ 12 (This output may alternately be used for LED)

IRQ 14  
IRQ 15 (This output may alternately be used for ring indicate)  
These bits determine which IRQ will occur when the card causes an interrupt through the RDY/  
-IREQ pin on the PC Card connector.  
Bit 4 Enable Manage Int  
Card status management interrupts occur as programmed by Management IRQ Select bits (bits  
0
1
7:4 of Management Interrupt Configuration register, see Bits 7:4 Management IRQ  
Selecton page 55).  
Card status management interrupts are redirected to the -INTR line instead of the programmed  
IRQ pin.  
This bit determines how management interrupts will occur.
